Misconception 1: CNC machining can only be used for mechanical machining
Many people believe that CNC machining is only suitable for mechanical machining, but in fact, the application range of CNC machining is very wide. In addition to traditional mechanical processing, CNC machining can also be applied in fields such as jewelry, medical equipment, aerospace, etc.
Misconception 2: The faster the CNC machining speed, the better
High speed is a major characteristic of CNC machining, but the faster the speed, the better. During the machining process, it is necessary to choose the appropriate rotational speed and feed rate based on factors such as material hardness, tool quality, and cutting conditions. Excessive speed may lead to increased tool wear and even damage.
Misconception 3: CNC machining does not require manual intervention
Despite the highly automated nature of CNC machining, manual intervention is still required in practical operations. For example, preparation work such as workpiece clamping and tool adjustment needs to be carried out before processing; During the machining process, it is necessary to monitor the cutting status and adjust parameters in a timely manner; After processing, quality inspection and cleaning work are required.
Misconception 4: CNC machining accuracy does not require manual control
Many people believe that CNC machining has high precision and does not require manual control. In fact, the accuracy of CNC machining is influenced by various factors, such as tool wear, cutting heat, and the accuracy of the machine tool itself. To ensure machining accuracy, it is necessary to regularly check the condition of the cutting tools and machine tools, as well as adjust machining parameters.
Misconception 5: CNC machining can only use metal materials
CNC machining is not limited to metallic materials, but can also be applied to non-metallic materials such as plastics, ceramics, etc. For different materials, it is necessary to choose appropriate cutting tools and processing parameters.
Misconception 6: CNC machining does not require traditional process skills
Although CNC machining has the characteristics of high automation, it does not mean that traditional process skills are not required. Before CNC machining, it is necessary to conduct process analysis and design to determine a reasonable machining route and parameters. In addition, operators also need to have certain basic knowledge and skills in mechanical manufacturing to ensure the stability and reliability of the processing process.
Misconception 7: High CNC machining costs
Many people believe that CNC machining costs are high, but in fact, with the continuous progress of technology and intensified market competition, CNC machining costs have gradually decreased. Of course, the cost also depends on the specific processing requirements and application areas. In certain high-precision and high-efficiency situations, the cost of CNC machining may be relatively high. However, considering factors such as processing efficiency, accuracy, and stability, CNC machining is usually a competitive processing method.
